' To all whom, it may con/ca rn. 1

Be it known that I, RICHARD MARX, a citizen of the United States, residingin Phila delphia, Pennsylvania, have invented certain Improvements in Ink-Distributing Devices vide a device for performing the above-noted work which shall not only be of relatively simple and inexpensive construction, but' which shall also be of such a nature as to be 1 conveniently applicable to the ordinary forms of printing-presses without requiring their modification or costly alteration. These objects I attain as hereinafter set forth, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of aportion of'a I printing-press, showing my invention as ap-j pliedthereto. Fig. 2 is a vertical section of my improved ink-distributing device, show- 1 ing certain features of its detail construe-g tion. Fi 3 is an end elevation, partly in section, 0 the structureshown in Figs. 1 and .2. Fig. 4 is an elevation similar to that of Fig. 3, but illustrating one of the inking rollers in engagement with the plate of the printing-press. Fig. 5 is a modified form of my p artly in section, of a portion of the supporting structure for my improved inking attachment.

In the operation of presses of the Gordon and similar types great difficulty has been experienced in seourin a continuous and uniform distribution 0 ink' upon the inkingplate of the press, and in overcoming this trouble I provide a structure preferably carri'ed by the press in such manner as not to interfere with the operation-of its inking-rollers, which structure is provided with two rollers, one of which receives ink from a fountain and delivers it to the surface of a drum,

' while. the other roller or set of rollers takes the ink from the drum and delivers it to the plate of the press. Means are also provided, if desired, whereby a uniform delivery of ink is secured from the fountain to the surface of the drum. Y

.. inhuman-mi.

:end of an eccentric-ro In the above drawings, A represents a.por I tion of -the frame of a Gordon or similar ress havin an ink-plate a, which is ordinarify revolve by means of a pair of bevel-gears a and a i As shown in Fig. 2, I provide an L-shaped arm b, bolted to the main frame of the printing-press and carrying at its outer end a bracket B, (shownin detail in Fig. 6,) which serves as a support for a spindle or shaft 0,

extending over the plate a. Immovably held on'this spindle by means of a set-screw d is a drum D,'the greater portion of whose surface is cylindrical, although that portion adjacent to the plate a is plane and substan tially parallel with said plate. The drum D is hollow and has within it an ink-fountain E pivotally carried upon a pin 6 in such manner that it may be moved to cause its roller e to the surface of the plane portion of the drum. The position of this fountain may be regulated by a sleeve F, carried upon the spindle O and provided with a milled end portion f,

screwed or otherwise fixed to it. I This sleeve may be locked in any iven position by means of a milled-headed bo t f, which screws into the shaft C and which is provided with a collar f placed to engage the end of the sleeve F. Said sleeve-has an eccentric portion f upon which is a strap 6f, connected to one engages a suitable pin' e on the fountain. The amount of ink delivered by the fountain is governed by the position of the roller e, which is provided with a spindle c eccentrically sup orted' in bearings formed in the ends of the ountain E. One of these eccentric portions a has connected to it an arm 45?, through which passes a screw 6, carried by the fountain E and provided with a milled nut e the arm being continually forced away from the fountain by means of a spring 6 on the screw,v

Journaled in the bracket B is a shaft 1), having a worm b, which meshes with a wormwheel 6 upon the shaft 0. This worm is fixed in any desired manner to a frame G,

which consists of a pair of rollers carrying arms 9 and'gf, rigidly connected by a cross' piece 9 and two sets of inclinedbraces 9 the roller-carrying arms being journaled on the sleeve F on opposite sides of the druml). The pair of arms you opposite sides of the drum are hollow, and each carries a plunger 9 which plungers in turn carry at their ends whose outer end project fora greater or less distance beyond plates 9 provided with bearings for spindles g on which are rollers g Springs g extend between suitable pins upon the plates 9 and screw upon the inner portions of the frames G and G in such manner as to maintain the rollers g continually in engagement with some portion of the surface of the drum D. The arms 9 each has hinged to its outer end an arm H, and the outer ends of these arms are connected by means of a spindle h, on which is a roller it, maintained in contact with the cylindrical portion of the surface of the drum D by means of springs 7L2, acting upon lugs h formed as part of or attached to the arms H. I preferably provide a stop it upon either or both of the arms g, so placed as to engage the lugs 71 so as to prevent the springs W from turning the arms H too far up on their pivots 7L5.

Upon the inclined connecting-braces g of the frame G, I place a pin 9 designed to cooperate with a star-wheel e on the spindle e of the inking-fountain roller, whereby said spindle will be turned through a fraction of a revolution upon each revolution of saidframe.

In order to more perfectly distribute the ink, as hereinafter described, I also provide a revoluble disk J, whose outer surface is flush with the plane surface of the drum D and which has fixed to its spindle j a wheel j. This latter is designed to be moved through a fraction of a revolution by each revolution of the frame G by means of a pin 9 placed to engage the teeth of said wheel.

As shown in Fig. l, the shaft 5 is in the present instance provided with a sprocketwheel which is driven from the main shaft K of the printing-press by means of sprocketchains is It and a shaft k having two sprocketwheels 1: and is. This latter shaft is in the line of the axis of oscillation of that part of the press-frame A which is designed to be swung backward and forward in the wellknown manner to print when the machine is in operation, and as a consequence of such construction said shaft 1/ always remains at the same distance from the shaft k thereby making possible the use of the chain-drive shown.

Under 9 crating conditions the spindle b, which is c iven from the main shaft K, as above described, drives the frame G and its rollers g arid h, so that these latter revolve continuously around the drum in the direction of the arrow in Fig. 3. With the fountain E properly supplied with ink it will be seen that on each revolution of the frame G the rollers 9 will by en aging the inkingfountain roller 6 carry in: therefrom to the cylindrical surface of the drum D, this ink being more or less distributed upon said latter rollers by means of the disk J, which is inter mittently rotated by the projection gr striking the wheel 9'. The roller it can never engage the plane portion of the drum D, since the stop 7L prevents its moving inwardly under the action of the spring 7L2 when it is adjacent to this part. It does, however, collect ink from the cylindrical surface of the drum D and deposits this upon the surface of the plate a, it being noted that the arms H turn upon their pivots 7L5 against the action of the spring 7& in order to permit this action, as shown in Fig. 4. The springs 9 cause the rollers g to always remain in contact with the drum D, thereby preventing them from ever coming in contact with the plate a, so that ink from the fountain is first delivered to the cylindrical surface of the drum by these rollers g and then collected by the roller h and delivered to the )late a. It will be noted, further, that the racket I) is so placed that the device above described is supported in such manner that the roller 72 moves across the plate a in a line at right angles to the line of motion of the main inkingrollers of the printing-press, (indicated at a") and as a result the ink is delivered to these main rollers at what is practically a perfectly uniform rate, being evenly distributed upon the plate a, and hence upon said rollers.

As above noted, the supply of ink may be adjusted to the utmost nicety by means of the sleeve F and the nut 0 If for any reason it should be found advisable, the rollersupporting frame may be constructed as shown in Fig. 5 at G, with the arms g and g ninety degrees apart instead of opposite to one another. In such case the braces 9 could be modified, as shown, and the connect ing member g made to extend across the drum D between the rollers g and it.

As shown in Figs. 2 and 6, the bracket B is held to the arm b by bolts, of which one is illustrated at I), and said bracket has slotted openings 6 for the reception of said bolts, whereby it is possible to adjust the distance of the drum and its parts from the plate a.
